New TRF 416 chassis parts

The new main chassis plates and and top decks arrived and have been tested for torsional stiffness. The test was a simple arrangement just to get some information about the stiffness of diffrent carbon fibre materials.  Here are the results: 

Supertec 5 cell 2 mm main chassis – 6 % stiffer than the standard 416 chassis (both new, never run)

Supertec 2 mm CRP top deck – 7,5 % softer than standard 416 top deck

Supertec 2 mm Carbon fibre top deck – 22 % stiffer

Supertec 2,3 mm Carbon fibre top deck – 46 % stiffer

Soon these parts will be track tested.

February testing

We continue the 416 testing program with a one day test on a bigger fast flowing track and again the car feels really good. Having rebuilt the car in the week before I started with the standard set up.  I managed to test diffrent motor and speed control setups and batteries. On the chassis I tried, battery position, roll bars and ackerman while monitoring tyre temperatures and laptimes all day. 

Next weekend it is my first race with the TRF416 and I will use basically the same setup as on the test. I only need to figure out what is the best way to take away a bit of corner turn in steering, then the car should be ready for the race.

TRF 416 development chassis parts

We are soon to test new chassis parts for the TRF 416. The new upper deck will be 2,4 mm and assembling this in the car will be a fast and simple way to test the effect of less chassis flex.

The 6 cell main chassis is a direct copy of the standard chassis but made from high grade carbon fiber in 2,0 or 2,4 mm. We have also designed a 5 cell chassis with the battery position optimized. The chassis parts will be made from high grade carbon fiber. The torsional stiffness will be measured and compared with the standard chassis.
